Question

why do sclerenchyma cells have a narrow lumen ? where are these tissues present and why?​

Answer 1

The cells of this tissue are dead. They are long and narrow as the walls are thickened due to lignin, a chemical substance, which acts as a cement and hardens them.

lumen are cavities present inside the cell,cells of sclerenchyma tissue have narrow lumen because sclerenchyma are strongly lignified which lead to compressing the cell and thus only narrow cavity is left.
